Moody

My jaw hurts, I hate my job and it hates me back, I miss my husband (at school) and am about to be missing my almost 3 year old son for a month + (grandma's).
I feel like I need a tranquilizer for peak stress times, all the "mood stabilizers" are not working and some of them make it worse. No one in the position to help me seems to understand or is willing to help. Very frustrated and depressed.
A little concerned something hormonal is going on, either pregnancy or really bad PMS.
